Blackmagic Design ATEM Mini Extreme ISO – HDMI Switcher

Product Overview

The Blackmagic Design ATEM Mini Extreme ISO is an eight-input HDMI live production switcher for streaming, with an integrated control panel and advanced broadcast features. It streams over RTMP, outputs as a USB webcam, and records all eight inputs plus program as individual MP4 files, automatically generating a DaVinci Resolve project for later editing.

Product Description

The ATEM Mini Extreme ISO accepts eight independent HDMI inputs up to 1080p60, each with its own frame-rate and format converter plus re-sync for switching between cameras, game consoles, and computers. You switch, add effects, color grade, and key in real time from the control surface or software panel, with CCU control for Blackmagic Studio, URSA, Micro Studio, and Broadcast cameras.

It supports nine M/E layers with four upstream and two downstream keyers, up to four chroma and four linear keyers, two DVE with borders and drop shadow, five pattern generators, and two color generators. Stream over Ethernet or use the USB-C output as a webcam recognized by Zoom, Teams, Skype, OBS, and XSplit; 5G/4G phone tethering over USB provides mobile data and automatic failover while powering the phone. ISO recording captures each input and the program as MP4 to USB disks, with a DaVinci Resolve project saved for cleanup. HDMI outputs feed monitors and support up to 16-screen multi-view.
